EOS software evolution enabling LHC Run 3 / Caffy, Cedric (CERN) ; Amadio, Guilherme (CERN) ; Guenther, Jaroslav (CERN) ; Lekshmanan, Abhishek (CERN) ; Mascetti, Luca (CERN) ; Peters, Andreas (CERN) ; Reis, Manuel (CERN) ; Simon, Michal Kamil (CERN) ; Sindrilaru, Elvin (CERN) ; Smith, David (CERN)
EOS has been the main storage system at CERN for more than a decade, continuously improving in order to meet the ever evolving requirements of the LHC experiments and the whole physics user community. In order to satisfy the demands of LHC Run-3, in terms of storage performance and tradeoff between cost and capacity, EOS was enhanced with a set of new functionalities and features that we will detail in this paper.First of all, we describe the use of erasure coded layouts in a large-scale deployment which enables an efficient use of available storage capacity, while at the same time providing end-users with better throughput when accessing their data.

Operation of the CERN disk storage infrastructure during LHC Run-3 / Caffy, Cedric (CERN) ; Amadio, Guilherme (CERN) ; Rios, Maria Arsuaga (CERN) ; Reis, Manuel Batalha (CERN) ; Capitoni, Niccolo (CERN) ; Contescu, Cristian (CERN) ; Guenther, Jaroslav (CERN) ; Mascetti, Luca (CERN) ; Peters, Andreas (CERN) ; Sindrilaru, Elvin (CERN) et al.
The CERN IT Storage group operates multiple distributed storage systems to support all CERN data storage requirements. The storage and distribution of physics data generated by LHC and non-LHC experiments is one of the biggest challenges the group has to take on during LHC Run-3.EOS [1], the CERN distributed disk storage system is playing a key role in LHC data-taking.

I/O performance studies of analysis workloads on production and dedicated resources at CERN / Sciabà, Andrea (CERN) ; Blomer, Jakob (CERN) ; Canal, Philippe (Fermilab) ; Duellmann, Dirk (CERN) ; Guiraud, Enrico (CERN) ; Naumann, Axel (CERN) ; Padulano, Vincenzo Eduardo (CERN) ; Panzer-Steindel, Bernd (CERN) ; Peters, Andreas (CERN) ; Schulz, Markus (CERN) et al.
The recent evolutions of the analysis frameworks and physics data formats of the LHC experiments provide the opportunity of using central analysis facilities with a strong focus on interactivity and short turnaround times, to complement the more common distributed analysis on the Grid. In order to plan for such facilities, it is essential to know in detail the performance of the combination of a given analysis framework, of a specific analysis and of the installed computing and storage resources.
